This experiment was carried out during the two successive winter seasons of 2009/2010 and 2010/2011 at clay loam soil in the farm of Faculty of Agriculture, Moshtohor, Benha University, Kalubia governorate, Egypt to investigate the effect of N, P fertilizer levels and some bio-fertilizer types which included Rhizobium, Phosphorein and Rhizobium plus Phosphorein in combination with mineral N and P fertilizers on vegetative growth and chemical composition of plant foliage as well as green pods yield and its components and dry seeds yield of pea plants cv. Master B. These treatments were arranged in complete randomized blocks design with four replicates. The results revealed that application of 100% and 50% of the recommended dose for both N at (40 and 20 kg N/fed.) and P at (31 and 15.5 kg P2O5/fed.) in the form of combination Rhizobium and Phosphorein significantly increased stem length, number of leaves and branches / plant , fresh, dry weight / plant, But delayed flowering, Also, it showed an increment in Photosynthetic pigments of leaves (chlorophyll a, b and a+b as well as carotenoids), N, P, K and crude protein percentage of foliage, number and weight of pods / plant, total green pod yield, average pod length, pod diameter, pod weight, number and weight of seeds / pod, netting percentage, weight of 100 dry seeds, N, P, K and protein percentage in pea seeds and dry seed yield followed by (Rhizo. + Phosp. + 25% of N + P2O5), ( Rhizo.+ 100% N), (Rhizo. + 50% N), (Phosp. + 25% P2O5), ( Rhizo. +25% N), mineral fertilizers with combination of nitrogen and phosphorus in a recommended levels then bio-fertilizers (Rhizobium and Phosphorein) compared to the both seasons.
